116 Observations on the Hervitisies and Storms 
7. After reaching the more northern latitudes, and while pursuing 
’ their course to the northward and eastward, these storms commence 
with the wind from an eastern or southern quarter, and terminate with 
the wind from a western quarter, as will appear more distinctly un- 
der the three following heads ;—the latter portion of the storm being 
usually attended with broken or clear weather. 
8. On the outer portion of the track, north of the parallel of 30°, 
or within that portion of it which lies farthest from the American 
coast, these storms exhibit at their commencement, a southerly wind 
which, as the storm comes over, veers —— to the westward, in 
which quarter it is found to terminate. ; 
9. In the same latitudes, but along the central portions of the track 
the first force of the wind, is from a point near to south-east, but af- 
ter blowing for a certain period, it changes suddenly, and usually af- 
ter a short intermission, to a point nearly or directly opposite to that 
from which it has previously been blowing, from which opposite quar- 
ter it blows with equal violence till the storm has passed over or has 
abated. This sudden change of a south-easterly wind to an opposite 
direction, does not occur towards either margin of the storm’s track, 
but only on its more central portion, and takes effect in regular pro-— 
gression along this central part of the route, from the south-west to- 
wards the north-east, in an order of time, which is exactly coincident 
with the progress of the storm in the same direction. It is under 
this portion of the storm, that we notice the greatest fall of the ba- 
rometer, and the mercury usually begins to rise a short time previous 
to the change of wind. «In this part of the track, the storm is known 
as a south-easter, and is usually attended with rain — to - 
change of wind, and perhaps for a short time after. 
10. On that portion of the track which is nearest the American 
coast, or which is farthest inland if the storm reaches the continent, 
the wind commences from a more eastern or north-eastern point of 
the horizon, and afterwards veers more or Jess gradually, by north, 
to a north-western or westerly quarter, where it finally terminates. 
Here also the first part of the storm is usually, but not always attend- 
ed with rain, and its latter or western portion with fair weather. The 
first or foul weather portion of the storm, is on this part of its track, 
recognized as a north-easter. 
It should be noted, however, that near the latitude of 30° and on 
the shores of Carolina, where the storm enters obliquely upon the 
coast, while its track is rapidly changing from a northwardly to an
